What is a good, fairly fast growing, shade tree? In Salem area, where are some places where the tree might be purchased?
Marion County Oregon
Picking out a tree is really a personal decision and there are many, many options. Frankly, I'd suggest a visit to the Oregon Garden in Silverton to have a look at all they have there. You can find out information about trees at the OSU Landscape plant site, most of which deals with plants in western Oregon:
Also there are resources through the Oregon Association of Nurseries available here:http://plantsomethingoregon.com/
Feel free to write with questions.
